Zinc soap and Zn/Ba mixed metal soap were synthesized and PVC plastisol with mixed metal soap and various costabilizers were also synthesized with good structures and characterized by IR and $^1H$-NMR. The IR spectrums and $^1H$-NMR spectrums of the synthesized soaps were in very good accordance with the structures proposed by earlier workers. In using phosphite as a costabilizer, TIDP phosphite was shown to be the excellent thermal stabilization effect at the low temperature and TNPP phosphite was shown to be the excellent thermal stabilization effect at the high temperature. In case of antioxidant, it was revealed that antioxidant was not effective in the low temperature thermal stabilization effect while highly effective in the high temperature thermal stability. $NaClO_4$ solution with sorbitol solvent had the best thermal stabilization effect among $NaClO_4$ solution series at low and high temperature.

Objectives : Many people use natural soap instead of commercially available bar type general soap for skin care. They tend to prefer cp (cold process) type soaps that go through a sufficient maturation process in formulation. The purpose of this study was to investigate the efficacy of PCPS (placenta cp soap). Methods : The researcher selected 36 subjects, 28 as the experimental group and 8 as the control group. I asked participants to wash their face twice a day in the morning and evening, and the period was set for 6 weeks. The researcher had the people who were selected as the control group use a commercially available foam cleanser, meanwhile the experimental group use PCPS. They performed a skin test before the start of the test, and the change status was continuously investigated after 2 weeks, 4 weeks, and 6 weeks after using the soap. Results : In the case of U zone oil and pores, there was a significant decrease and in the case of skin tone, there was a significant increase in the group of using PCPS. In T zone oil change, there was no significant effect in both the experimental group and the control group. Conclusion : In the case of PCPS, it is recommended to use it in the effect of reducing the size of pores and increasing skin tone, but it can reduce u-zone oil content.

Forty two Malpura lambs (21 d old) were divided into three groups of 14 each consisting of 8 females and 6 males. Lambs were allowed to suckle their respective dams twice daily up to weaning (13 wks) and offered free choice concentrate and roughage in a cafeteria system. The lambs in control group were fed conventional concentrate mixture, in RBO group concentrate mixture fortified with 4% industrial grade rice bran oil and in Ca-soap rice bran oil (as in RBO group) was supplemented in the form of calcium soap. The concentrate intake decreased($p{\leq}0.05$) in RBO group as a result total dry matter, crude protein and metabolizable energy intake decreased compared to control whereas Ca-soap prepared from the same rice bran oil stimulated the concentrate intake leading to higher total dry matter, crude protein and energy intakes. The digestibility of dry matter ($p{\leq}0.05$), organic matter ($p{\leq}0.05$) and crude protein ($p{\leq}0.05$) was higher in RBO group followed by Ca-soap and control whereas no effect was observed for ether extract digestibility. Higher cholesterol ($p{\leq}0.05$) content was recorded in serum of oil supplemented groups (RBO and Ca-soap) while no effect was recorded for other blood parameters. Rice bran oil as such adversely affected and reduced the body weight gain ($p{\leq}0.001$) of lambs in comparison to control whereas the Ca-soap of rice bran oil improved body weight gain and feed conversion efficiency in lambs. Fat supplementation decreased total volatile fatty acids ($p{\leq}0.05$) and individual volatile fatty acid concentration which increased at 4 h post feeding. Fat supplementation also reduced ($p{\leq}0.05$) total protozoa count. Ca-soap of rice bran oil improved pre slaughter weight ($p{\leq}0.05$) and hot carcass weight ($p{\leq}0.05$). It is concluded from the study that rice bran oil in the form of calcium soap at 40 g/kg of concentrate improved growth, feed conversion efficiency and carcass quality as compared to rice bran oil as such and control groups.

1. 연감시료량의 적정량을 알아보기 위해 200, 100, 50, 20, 10gr의 생사시료를 연감검사한 결과 각처리간에는 통계적차이를 인정할 수 없었으나 실제로 시료량의 과대 과소에 따른 측정 및 처리오차를 감안할 때 100gr 시료가 적정량이었다. 2. 섬도사를 이용하여 연감검사를 할 경우 꼬인 상태와 풀은 상태로 연감처리할 경우 탄산나트륨같이 제교력이 강한 정연제에서는 차이가 없었으나 Marseilles 비누같이 제교력이 약한 것은 연감율에 있서 현저한 차이가 있었다. 3. 5종의 정연제를 비교한 결과 합성세제와 국산 Marseilles비누와 통계적 유의차를 인정 할 수 없으므로 이와의 대체 이용이 가능하다. 4. 정연제의 제교력은 대체로 정연액의 PH가 클수록 크고 작을수록 작은 경향이 있다.

최근의 급속하게 변화하는 모바일 인터넷 환경에서 이전의 웹 서버 성능으로는 사용자의 빈번한 연결 요구에 대해 적절한 대응이 어렵기 때문에 웹 서비스 엔진의 성능 향상이 필요하다. 따라서 본 논문은 웹 서비스의 성능 향상을 위해서 부가적으로 설치하는 톰캣 서블릿 컨테이너와 무관하게 사용자의 접속 요청을 처리하고, SOAP(Simple Object Access Protocol) 메시지 처리 시간을 단축하는 모바일 웹 서비스의 서버 구조를 제안한다. 제안한 웹 서버 구조는 사용자요구 수신기, 웹 문서 처리기, SOAP 프로토콜 처리기, NBTM(Non-Blocking and Thread Manager) 관리자, 세션 관리자로 구성한다. 제안된 시스템은 표준 램 서비스 프로토콜을 완전하게 지원하고, 웹2.0의 모바일 웹서비스 시스템의 통신 오버헤드와 메시지 처리 시간, 서버의 오버헤드를 감소하며, 웹2.0 환경에서 구현 실험을 통한 지연 수행 평가에 의해서 웹2.0표준 모바일 웹 서비스 시스템과 성능을 비교, 평가하여 성능 향상을 확인하였다.

Objectives : To maintain a healthy skin condition, the role of moisture in the stratum corneum is important. We use soap in our daily life, so we wanted to observe the changes of the skin moisture using herbal CP soap. Four kinds of herbal CP soaps were prepared and their effects on skin moisture were compared. Methods: We surveyed 39 students at A University to determine their subjective skin condition, lifestyle and washing habits. Then, a facial analysis test was performed. We made herbal CP soaps using Kyungohkgo, Hwangryunhaedoktang, Seosiokyongsan and Baeksoooh and distributed them to experiment participants. Prior to the experiment, their skin condition was checked and skin condition was assessed using Facial Diagnosis System three times in total. After the experiment, the change of skin was measured and analyzed. Results: As a result of examining the skin moisture according to the using of the herbal CP soap by the participants, the skin moisture was gradually increased compared with before use. The moisture content increased after 6 weeks of use compared to before using Seosiokyongsan, Hwangryunhaedoktang, Kyungohkgo CP soap compared to before use. But there was no significant difference between 3 weeks and 6 weeks of use compared to before use. As a result of using Baeksoo-oh CP soap, the skin moisture of the experimental participants was continuously increased. Conclusion: Natural CP soaps are believed to have a beneficial effect in increasing the moisture content of facial skin.

Objectives : In previous studies, I presented various effects of Seosiokyongsan (SSOOS) cp soap on facial skin. However, in the case of skin clinical trials, various factors such as lifestyle, alcohol, tobacco, and stress could not be excluded. The purpose of this study was to investigate the effect of face wash using SSOOS cp soap on the skin without environmental factors. Methods : The same water and towel were used at the same place in order to examine the skin change state immediately before and after washing face with SSOOS cp soap. The skin test was performed before washing the face and after 10 minutes washing the face to compare the changes. As a control group, the case of washing with water without using cleanser and the case of washing with S-K cleanser, which is a popular commercial product, were set. Three cases were compared and analyzed. Results : In the case of water washing, the decrease in moisture was similar to that of the S-K cleanser and the amount of oil and pores decreased, but it was weaker than that of the S-K cleanser. The SSOOS cp soap showed a decrease in oil, pores, and pigments, but it was not significant, the moisture showed a significant decrease, but it was mild compared to S-K cleanser and water wash. Conclusion : In the case of SSOOS cp soap, the stimulation caused by facial cleansing was the least, showing a gentle change.

식물성지방산 고형비누는 검화법으로 제조 후 수분증발 및 경도를 위하여 건조과정이 필요하다. 본 연구에서는 합성향료를 대체하여 휘발성이 높은 에센셜오일을 혼합하여 비누 제조시 비누에 포함된 에센셜오일(라벤더오일)의 주요 향기성분(리나롤, 리나릴 아세테이트)이 건조기간 및 첨가물(이산화티탄)에 따라 변하는 향의 지속기간을 GC-MS를 이용하여 비교 관찰하고자 하였다. 그동안의 연구는 식물성고형비누의 사용성에 관한 연구가 대부분이었으며, 향의 휘발성과 관련된 연구는 미비한 상태이다. 비누에 포한된 리나롤의 휘발성은 이산화티탄을 혼합한 비누가 12주까지 감소율이 높게 나타났으나, 20주가 되는 시점에서는 유사한 수준으로 감소되었다. 리나릴 아세테이트는 이산화티탄의 혼합여부에 따라 약간의 차이를 보이기는 했으나 20주경과 시점까지 휘발성이 유사하게 나타났으며, 건조 20주 동안 리나릴 아세테이트보다 리나롤의 잔존율이 이산화티탄의 혼합여부와 상관없이 높게 나타났다. 상온에서 2일정도의 지속성을 갖는 라벤더 에센셜오일의 향 성분이 식물성 지방산 고형비누와 혼합하여 제조시 20주(5개월)동안 비누에 잔존하고 있음을 확인 할 수 있었다.
